Re: TCPIP get/set hostname always fails

I am seeing the same problem, however it was intermittent. This makes me think there is a timing or race condition causing the problem. At my current app code level though, it is failing every time. I am on the ESP-IDF Pre-release v4.0-beta2. The correct place to set the host is after start and befo...

Re: Deep sleep edge wake-up

I also believe that having an either-edge trigger is ideal for wakeup scenarios. A simple open/close sensor easily exhibits the issue with only having hi or low wakeup trigger: 1. I don't want an installer of my product to have to make sure the sensor is open or closed to begin with. If the code sta...

Re: uSD card using SPI and fwrite() consistently fails after short operating period

I have not found a solution. I tried various level API's to do the card IO but always the same repeatable problem. There were some previous forum/internet discussions on timeouts related to SD card operations so search for that and there may be an answer for your timeout issues. I have tried multipl...

If you are using C++, std::regex works fine.

Re: Use external micro-SD card vs. the built-in one on the ESP32 Wrover Kit V3

I want to use/test a single SD card reader (the one I will use in a production system) vs. the on-board one. There is physical circuitry connected to the on-board card reader with various pull-ups (10K 1%) and voltage-suppressor diodes on the lines. I am still pretty new to electronics design and th...

Re: Use external micro-SD card vs. the built-in one on the ESP32 Wrover Kit V3

In any case, physically removing the SD card (media itself) and using it elsewhere is not the issue. Perhaps my question needs to be clarified? The question is: Do I need to disable the on-board SD card reader circuitry before I use the same GPIO to attach to an external SD card reader? I looked at ...

Re: Unexpected break/watch point in FreeRTOS code cannot be resumed

Thank you for the response. Can memory issues (heap, stack) etc... somehow cause this problem? I asked this in the original post and am wondering if I should be looking at other potential causes. I will try to get a standalone example. Currently I cannot send you my entire environment (licensing, et...
